%description
Dnsmasq provides network infrastructure for small networks: DNS,
DHCP, router advertisement and network boot.

The DNS subsystem supprots forwarding of all query types, and caching
of common record types, DNSSEC included. The DHCP subsystem supports
DHCPv4, DHCPv6, BOOTP and PXE. RA can be used stand-alone or in
conjunction with DHCPv6.
